Instrument TerminologyRefer to the following list for definitions of common PXIe-5831 instrument terms usedthroughout this document.
Table 1. Instrument Terminology Definitions
Term Definition
IF IN/OUT Ports Refers to the IF IN/OUT 0 and IF IN/OUT 1 connectors on thePXIe-3622 front panel for intermediate frequency (IF) signals.
TRX Ports Refers to the DIRECT TRX PORTS orSWITCHED TRX PORTS on the mmRH-5582 front panel forRF signals.
DIRECT TRX PORTS RF connectors 0, 1, or 8 on mmRH-5582 modules labeled withDIRECT TRX PORTS.
SWITCHED TRX PORTS RF connectors 0 through 7 or 0 through 15 on mmRH-5582modules labeled with SWITCHED TRX PORTS.
LO1 Refers to the local oscillator responsible for the up and downconversion between IF and mmWave frequencies.
LO2 Refers to the local oscillator internal to the PXIe-3622responsible for the up and down conversion between basebandand IF.
Onboard Refers to the value of the LO Source property and changespurpose depending on the designated LO and instrumentconfiguration. A value of Onboard configures the hardware asfollows:• PXIe-5831 IF only instrument—LO1: N/A
LO2: Sets the source of LO2 to one of the internalsynthesizers of the PXIe-3622.
• PXIe-5831 IF and mmWave instrument—LO1: Sets thesource of LO1 to the PXIe-5653.LO2: Sets the source of the LO2 to one of the internalsynthesizers of the PXIe-3622.
Secondary Refers to the value of the LO Source property for LO1 in thePXIe-5831 IF and mmWave instrument configuration. Thevalue of Secondary sets the source of LO1 to the internalPXIe-3622 synthesizers.
This setting optimizes frequency settling time, but may worsenphase noise. NI recommends using this setting when LOsharing and speed optimization for spectral scanning ispreferred.
Offset Mode is Automatic Refers to the NI-RFSA Downconverter Frequency OffsetMode property or NI-RFSG Upconverter Frequency OffsetMode property set to Automatic.
The PXIe-5831 contains a direct conversion architecture.Offset mode allows the instrument to operate in low IF mode,which increases the separation between the signal of interestand the residual sideband image and residual LO leakagepower. However, low IF mode limits the availableinstantaneous bandwidth. A setting of Automatic allows thedriver to enable low IF mode when the signal bandwidth issmall enough to allow it.
Automatic is the default value. NI recommends keeping offsetmode set to the default value.
Offset Mode is Enabled Refers to the NI-RFSA Downconverter Frequency OffsetMode property or NI-RFSG Upconverter Frequency OffsetMode property set to Enabled.
The PXIe-5831 contains a direct conversion architecture.Offset mode allows the instrument to operate in low IF mode,which increases the separation between the signal of interestand the residual sideband image and residual LO leakagepower.
Offset Mode is User-Defined
Refers to the NI-RFSA Downconverter Frequency OffsetMode property or NI-RFSG Upconverter Frequency OffsetMode property set to User-Defined.
The PXIe-5831 contains a direct conversion architecture.Offset Mode set to User-Defined allows the instrument tooperate with maximum instantaneous bandwidth. By default,the offset is selected to maximize the available instantaneousbandwidth.
dBr For receivers, dBr refers to the power of a received signal withrespect to the instrument's configured reference level. Forexample, if the reference level is set to -10 dBm but thereceived tone is -7 dBr, the actual power of the received CW is-17 dBm.
For transmitters, dBr refers to the generated power of a CWwith respect to the instrument's peak power setting. Forexample, with a peak power level setting of +5 dBm and a-3 dBr setting, the power of the transmitted CW is +2 dBm.

1 Frequency range refers to the range of upconverter or downconverter center frequencies. Theactual frequency coverage extends beyond the upconverter or downconverter frequency by up tohalf of the frequency bandwidth.
2 The mmRH-5582 DIRECT TRX PORTS and SWITCHED TRX PORTS share the same frequencyranges and are only available on the PXIe-5831 mmWave instrument configurations.
3 Tuning resolution combines LO step size capability and frequency shift DSP implemented on theFPGA.
4 The worst case LO spurious content degrades for smaller LO step sizes and improves for larger LOstep sizes that are multiples of 2 MHz and 10 MHz.
5 LO step size can be set using the driver software.
6 LO1 Frequency Tuning Time consists of the PXIe-5653 Lock Time + PXIe-5831 (LO1) SettlingTime to Required Accuracy. The PXIe-5653 Lock Time is dependent on the RF Center Frequency(CF) frequency step change from initial frequency to final frequency. The relationship between theCF and the PXIe-5653 frequency is governed by the equation: F_PXIe-5653 = (FCF + FIF)/8. FIF isdetermined by the CF. For CF = 22.5 GHz to 31.3 GHz, FIF = 17.8 GHz; CF = >31.3 GHz to40 GHz, FIF = 12 GHz; CF = >40 GHz to 44 GHz, FIF = 9 GHz For example, for a CF step changefrom 28 GHz to 39 GHz, first calculate the equivalent FPXIe-5653 for 28 GHz, which is 5.725 GHz,then the equivalent CF frequency for 39 GHz, which is 6.375 GHz. The PXIe-5653 step size is6.375 GHz - 5.725 GHz = 650 MHz. The corresponding PXIe-5653 maximum frequency lock timeis 10 ms.

Conditions: 23 °C; peak output power is set to within -40 dBm to the RF output maximumleveled power specification for direct and switched TRX ports.
LO1 x 2 refers to out-of-band leakage where an LO1 harmonic product appears at the TRXport output as a function of the configured peak power level (hence dBr units), andupconverter center frequency (UCF). The relationship between the UCF frequency and theLO1 x 2 frequency is governed by the equation: FLO1x2 =(FUCF+FIF)/2. FIF is determined bythe UCF. For UCF = 22.5 GHz to 31.3 GHz, FIF = 17.8 GHz; UCF > 31.3 GHz to 40 GHz,FIF = 12 GHz; UCF >40.0 GHz to 44 GHz, FIF = 9 GHz. In the frequency range 22.5 GHz to31.3 GHz, the minimum frequency for FLO1x2 is when CF = 22.5 GHz and here FLO1x2 =20.15 GHz; the maximum frequency for FLO1X2 is when CF = 31.3 GHz and there FLO1x2 =24.55 GHz. In all cases, LO1x2 is out-of-band.
The in-band residual spurs are a function of the transmit tone power (hence dBc units) andare measured to within the instantaneous 1 GHz bandwidth. This does not include carrierleakage and residual image.
The out-of-band spur numbers refer to spurs that are offset from the upconverter centerfrequency between 500 MHz to 5 GHz away, but does not include the LO1 x 2. These spursare a function of the transmit tone power and hence have dBc units.
